CHEVROLET EXPRESS STARTER PROBLEM

2002 Chevrolet Express • 230,000 miles

I am searching and this seems to be the closest. I am mechanically inclined and have rebuilt a few motors in my day. Last year I removed and replaced my engine with used one. (02 exspr, van 5.7 automatic)i was able to get 30k out of it when it finally blew up on an interstate in MO. The tow guy agreed to swap a motor out for me.I found a rebuilt on 5 miles from his shop. They swapped it out and when I went to get it he said he couldn't use my smaller starter I had from my blow engine and that he had to use the larger style because he said the block must be older than my 02. Well I need the van so I left with it. A month later the starter spun out a few times. Then made the screeching noise and I was wondering if he shimmed it. I just tried both style small and large and dropped the pan while the starter engaged and noticed the bendix gears not meshing properly and that the flywheel looks like it needed replacement which I will do. Here is my question the large style starter when crossed at napa showed it for a 1992. Is the flywheels different from 1992 to 2002. I am trying to find the specs? I did shim one of the starters but that didn't help. The bendix gears didn't mess in all the way and there wasn't enough power to spin the motor with both styles. The engine does turn I rotated it by hand. So do I need to change the fly wheel to old style because the block casting may be different> > > > > > > >

Get the block casting number and call the dealer and they will tell you the year of the motor. Once you have that, get the flywheel and the matching starter and install. Make sure there are the correct bolt holes for the converter. Gm used that trans for many years so I think it should work
